subject: Summary And Analysis Of Slime Dryer [print this page] With mechanized mining of coal resources, coal is pulverized and the share of the end of the column increases. With the chase and in the coal washing plant to produce slime and coking coal washing practice increased coal flotation tail. Both are more and more slime out of coal by-products. As the slime has a fine grain size, water holding strong, high ash content and contain more clay, etc., for the utilization of slurry inconvenience, most of the washing plant sludge is sold to local farmers.
Coal slime drying machine, also called coal slime dryer, coal dewatering machine, coal slurry dryer, coal mud dryer, coal sludge dryer and so on. It is kind of highly efficient, stable and reliable heating drying equipment, designed to dry materials of high moisture or strong stickiness. Its performance are better than tube bundle rotary dryer, blade rotary dryer. Its features are big capacity, low energy cost, and high efficiency. Its applied in the materials like coal slurry, mud, filled gypsum, Muddy, high-moisture swell soil, electroplate mud and so on.
Large series of slime dryer mainly broken by the drum dryer, furnace, feed screw, a feed screw, pipes, dust, wind off device, fan, control cabinets and other components.
Using four dehydration process: a dry area to the feeding mainly in high humidity conditions, after transient inlet temperature 600 and the heat transfer and mass transfer slurry to remove most of the water, and difficult to fire; two drying area is ranked bonded area, the indoor temperature is 450 ; three drying area is downstream drying, room temperature 300 ; four dry zone is a high-drainage areas, the indoor temperature is 100 . The whole process is a low-temperature drying, sludge is not likely to cause burning, which can really play the energy saving effect. impact crusher:http://www.crusher-machine.com/2.html

How is the complete drying slime production line? Ore from the feed screw directly into the dryer drum crusher, drum wall is repeated on the copy board took a scattered, scattered through the crushing blow after installation, materials and negative pressure high-temperature media full access to complete heat and mass transfer process. As the drum inclination and lead sub-air role, the material slowly moving from the feed end, after drying the material by a screw discharge, exhaust gas through the precipitator dust, into the atmosphere.
